Research Objectives
Large-scale 3-D flow models have played a critical role in characterizing and assessing the effects of hydrogeologic, thermal, and geochemical conditions in the unsaturated zone (UZ) at Yucca Mountain, Nevada, the proposed site of the future U.S. nuclear waste repository. Our work involves developing and refining the current mountain-scale UZ flow model developed for use in the current Total System Performance Assessment for License Application (TSPA-LA) in connection with Yucca Mountain.
